There are too many waifus to choose from. This is gonna be difficult. Maybe Tenma from School Rumble is adorable. Yui, Ritsu or Tsumugi from K-on!, Kaname Chidori from Full Metal Panic. I enjoyed the relationship between Asuna and Kirito in Sword Art Online. It's impossible to forget about Nagisa and Tomoya's marriage from Clannad. Konata from Lucky Star, Haruko from Fooly Cooly. Dita - Vandread, Ringo - Air Gear.

Okita Souji from Hakuouki, I love his personality, and how he still has a positive attitude towards others regardless of what he is going through. He also seems to care deeply about others, and he is pretty. *_*

Or Okarin from Steins;Gate, I love that guy, he is smart and hilarious, and he cares a lot about the people close to him

The Demon King from Maoya. She seems to have a great deal of wisdom to share, but she is completely lost when it comes to relationships. I've liked the qualities of many an anime girl, but as you learn more about character types, you start to notice these are stereotypical qualities. I've never seen a character like The Demon king before. She is the first one that seems to scream KEEP ME. She understands contracts and what it means to give one's word to another. Plus when she removed the horns in ep. 1, I had to pause until I stopped laughing. Very cute.
